b. Calculate the coefficient of variation for these sample data and interpret its meaning.

answer is coefficient of variation=22.68860848
I don't know what it means by interpret it's meaning....

c. Using Tchebysheff's Theorem, determine the range of values that should include at least 89% of the data. Count the number of data values that fall into this range and comment on whether your interval range was conservative or not.
